An e-mail message sent Friday to Bistriceanu seeking comment was not immediately returned.

DiCaprio's request included statements from the actor and his security team claiming Bistriceanu had traveled from Chicago to Los Angeles at least twice to try to meet DiCaprio at his home and business office. She refused to leave the properties and acted aggressively, the court filings state.

The Academy Award-nominated actor wrote that she "has evidenced a willingness to make physical contact with me regardless of the consequences."

Bistriceanu has been placed on a psychological hold twice, according to the documents.

DiCaprio said he has never met Bistriceanu, but she has sent him numerous handwritten letters. Some were attached to his request for the restraining order and reviewed by the judge.

One letter included the greeting, "Dear husband Leo," and contained statements that Bistriceanu believed DiCaprio was the father of baby Jesus.
